Stable Isotope Analysis

The Chair of Analytical Chemistry and Water Chemistry at the Technical University of Munich (TUM) is committed to excellence in research, teaching and interdisciplinary education. We strive to proactively develop analytical tools for detecting health risks to humans and the environment, to better understand pollutants and pathogens dynamics, and to provide mechanistic insights for decision-makers and practitioners to better solve environmental challenges.

We are looking for a

PhD Student (m/f/d) in Instrumental
Analytical Chemistry

Compound-specific isotope analysis (CSIA) achieves highly precise measurements of stable isotopes in organic substances. 13C/12C measurements at natural isotope abundance can elucidate degradation of groundwater contaminants, prove doping in sports, and demonstrate adulteration in food science.

The underlying instrumentation of gas chromatographic separation followed by online combustion reactors and subsequent mass spectrometric analysis, however, requires (i) low method quantification limits and (ii) complete peak separation. Here, comprehensive gas chromatography (GCxGC) offers a powerful innovation, yet presently lacks sufficiently narrow combustion reactors for fast isotope analysis. To spearhead GCxGC for isotope ratio mass spectrometry (IRMS), the project therefore aims (i) to develop suitable miniature reactors and (ii) to modify hardware and software parts of an existing GC-IRMS system to enable GCxGC-IRMS.

In this project you will (a) develop miniature combustion reactors using methods of synthetic inorganic and organic chemistry; (b) modify all existing hardware and software components of a GC-IRMS system (combustion interface coupled to a MAT 253) to enable GCxGC-IRMS; (c) test and optimize the method for environmental samples; (d) closely collaborate with external partners.

Your Qualifications
Applicants must have completed a Master’s degree in analytical chemistry, geo- or environmental sciences (specialization: instrumentation of isotope analysis), mechanical engineering (specialization: analytical instrumentation, gas flow) or a closely related science field. Strong analytical and laboratory skills / craftsmanship, ideally professional training, in the modification of technical- / analytical equipment are required. Training and interest in analytical chemistry, isotope analysis, mass spectrometry and environmental analysis is an asset. An excellent standard of written and spoken English is required and knowledge of German is an advantage. In the scope of the project, collaboration with other research requires interpersonal skills, the interest to work in an interdisciplinary environment and to integrate into a team, as well as a high motivation for the project.


We offer
o   Working in an innovative, well-equipped and scientifically stimulating international environment.

o   Further training opportunities through the chair and the graduate school at TUM.

o    Remuneration according to standard public service salary (TV EntgO Bund EG 13, 65%) for three years’ duration.

o    Technical University of Munich is striving to increase the proportion of women; application from women are therefore expressly welcomed.

If you are highly motivated, enthusiastic and independent person with passion to conduct research, submit your application to Prof. Martin Elsner by email until 30 September 2021. Your application should include a cover letter, a complete CV, along with three references, relevant documents such as certificates, transcript of marks, theses and publications.

Master Theses

Laser-induzierte Breakdown-Spektroskopie LIBS zur Analyse von Aerosolen 

Die Entwicklung von Abgasmesstechnik ist einer der Schwerpunkte unserer Aktivitäten und derzeit ein höchst aktuelles Thema. Wir wollen untersuchen, in wie weit LIBS für diesen Zweck eingesetzt werden kann. Es gibt umfangreich Voruntersuchungen, aber nicht mit der spezifischen Anwendung in der Abgasmesstechnik.
Wie bei den meisten unserer Arbeiten ist das Thema überdisziplinär; besonders wichtig ist Freude am Experimentieren und "Basteln". Das Thema eignet sich besonders für angehende Physiker, aber auch für verwandte Disziplinen (Chemie, Chem.-Ing. etc.) mit den oben genannten Interessen.

Raman-Spektroskopie in mikrofluidischen Systemen

Ihre Aufgabe ist der Aufbau eines Raman-Systems zur Analyse von biologischen Proben in mikrofluidischen Kanälen. Die Anwendungen können etwa die Untersuchung von Bakterien oder Algen sein, die vereinzelt und festgehalten werden, aber auch Ensemble-Messungen in einem kontinuierlichen Durchfluss.
Wie bei den meisten unserer Arbeiten ist das Thema überdisziplinär; besonders wichtig ist Freude am Experimentieren und "Basteln". Das Thema eignet sich besonders für angehende Physiker, aber auch für verwandte Disziplinen mit den oben genannten Interessen.

Initiativbewerbung für Masterarbeiten

Wir bieten immer zahlreiche Themen für Masterarbeiten an, die nicht alle hier aufgeführt sind. Wenn Sie sich grundsätzlich für die von uns bearbeiteten Themenbereiche interessieren und Freude am Experimentieren haben, sollten Sie sich unbedingt bei uns melden; wir können gerne gemeinsam passende Themen und Projekte entwickeln, die sich spezifisch an Ihren Interessen orientieren.

Bachelor Theses

Themen für Bachelorarbeiten werden meist kurzfristig festgelegt und beschäftigen sich üblicherweise mit den anderen auf der Web-Seite genannten Themen.
